Approval and Promulgation of Air Quality Implementation Plans; District of Columbia;

Section 110(a)(2) Infrastructure Requirements for the 1997 8-Hour Ozone and the 1997 

and 2006 Fine Particulate Matter National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve submittals from the District of Columbia (the 

District) pursuant to the Clean Air Act (CAA) sections 110(k)(2) and (3). These submittals

implement, maintain, and enforce the 1997 8-hour ozone and fine particulate matter (PM2.5)

national ambient air quality standards (NAAQS) and the 2006 PM2.5 NAAQS. This proposed 

action is limited to the following infrastructure elements which were subject to EPA’s

completeness findings pursuant to CAA section 110(k)(1) for the 1997 8-hour ozone NAAQS 

dated March 27, 2008, and the 1997 PM2.5 NAAQS dated October 22, 2008: 110(a)(2)(A), (B),

SUPPLEMENTARY INFORMATION: 

I. Background 

On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS (62 FR 38856) and a new 

PM2.5 NAAQS (62 FR 38652). The revised ozone NAAQS is based on 8-hour average 

concentrations. The 8-hour averaging period replaced the previous 1-hour averaging period, and 
4

the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm. The new 

PM2.5 NAAQS established a health-based standard of 15.0 micrograms per cubic meter (μg/m3) 

based on a 3-year average of annual mean PM2.5 concentrations, and a 24-hour standard of 65

μg/m3based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA 

strengthened the 24-hour PM2.5 NAAQS from 65 μg/m3to 35 μg/m3on October 17, 2006 (71 FR 

61144). 

Section 110(a) of the CAA requires States to submit State Implementation Plans (SIPs) that 

provide for the implementation, maintenance, and enforcement of new or revised NAAQS within 

three years following the promulgation of such NAAQS. In March of 2004, Earthjustice initiated 

a lawsuit against EPA for failure to take action against States that had not made SIP submissions 

to meet the requirements of sections 110(a)(1) and (2) for the 1997 8-hour ozone and PM2.5

NAAQS, i.e., failure to make a “finding of failure to submit the required SIP 110(a) SIP 

elements.” On March 10, 2005, EPA entered into a Consent Decree with Earthjustice that 

obligated EPA to make official findings, in accordance with section 110(k)(1) of the CAA as to 

whether States have made complete SIP submissions, pursuant to sections 110(a)(1) and (2), by

December 15, 2007 for the 1997 8-hour ozone NAAQS, and by October 5, 2008 for the 1997 

PM2.5 NAAQS. EPA made completeness findings for the 1997 8-hour ozone NAAQS on March 

27, 2008 (73 FR 16205) and on October 22, 2008 (73 FR 62902) for the 1997 PM2.5 NAAQS. 

These completeness findings did not include findings relating to: 1) section 110(a)(2)(C) to the 

extent that such subsection refers to a permit program as required by Part D Title I of the CAA; 

2) section 110(a)(2)(I); and 3) section 110(a)(2)(D)(i), which has been addressed by a separate 
5

finding issued by EPA on April 25, 2005 (70 FR 21147). Therefore, this action does not cover 

these specific elements.

 

II. Summary of State Submittal

The District provided multiple submittals to satisfy section 110(a)(2) requirements, that are the 

subject of this proposed rule for the 1997 8-hour ozone NAAQS and the 1997 and 2006 PM2.5 

NAAQS. The submittals dated December 6, 2007 and January 11, 2008 addressed the 110(a)(2) 

requirements for the 1997 8-hour ozone NAAQS; the submittals dated August 25, 2008 and 

September 22, 2008 addressed the 110(a)(2) requirements for the 1997 PM2.5 NAAQS; and the 

submittal dated September 21, 2009 addressed the section 110(a)(2) requirements for the 2006 

PM2.5 NAAQS. These submittals addressed the following infrastructure elements, that are the 

subject of this proposed rule: 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and 

(M). 

 

EPA has analyzed the above identified submissions and is proposing to make a determination 

that such submittals meet the requirements of 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), 

(J), (K), (L), and (M). A detailed summary of EPA’s review of and rationale for approving the 

District’s submittals may be found in the Technical Support Document (TSD) for this action

which is available on line at www.regulations.gov, Docket number EPA-R03-OAR-2010-0139. 

III. Proposed Action

EPA is proposing to approve the District of Columbia’s submittals that provide the basic 
6

program elements specified in the CAA sections 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), 

(J), (K), (L), and (M) necessary to implement, maintain, and enforce the 1997 8-hour ozone and 

PM2.5 NAAQS and the 2006 PM2.5 NAAQS. EPA is soliciting public comments on the issues 

discussed in this document. These comments will be considered before taking final action. 

IV. Statutory and Executive Order Reviews 

Under the CAA, the Administrator is required to approve a SIP submission that complies with 

the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 

52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided 

that they meet the criteria of the CAA. Accordingly, this action merely proposes to approve state 

law as meeting Federal requirements and does not impose additional requirements beyond those 

imposed by state law. For that reason, this proposed action:

 is not a "significant regulatory action” subject to review by the Office of Management and 

Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); 

 does not impose an information collection burden under the provisions of the Paperwork 

Reduction Act (44 U.S.C. 3501 et seq.);

 is certified as not having a significant economic impact on a substantial number of small 

entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); 

 does not contain any unfunded mandate or significantly or uniquely affect small 

governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 

104-4);
7

 does not have Federalism implications as specified in Executive Order 13132 (64 FR 

43255, August 10, 1999);

 is not an economically significant regulatory action based on health or safety risks subject 

to Executive Order 13045 (62 FR 19885, April 23, 1997); 

 is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, 

May 22, 2001); 

 is not subject to requirements of Section 12(d) of the National Technology Transfer and 

Advancement Act of 1995 (15 U.S.C. 272 note) because application of those 

requirements would be inconsistent with the CAA; and 

 does not provide EPA with the discretionary authority to address, as appropriate, 

disproportionate human health or environmental effects, using practicable and legally

permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
8

In addition, this proposed rule, pertaining to the District of Columbia’s section 110(a)(2)

infrastructure requirements for the 1997 8-hour ozone and PM2.5 NAAQS and the 2006 PM2.5 

NAAQS, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, 

November 9, 2000), because the SIP is not approved to apply in Indian country located in the 

state, and EPA notes that it will not impose substantial direct costs on tribal governments or 

preempt tribal law.
